this is so difficult

what is a private uninitialized field?

GoKart.java 
public class GoKart {
  private String mColor;
  public static final int MAX_BARS = 8;
  private mBarsCount;
    mBarsCount = 0;
  public GoKart(String color) {
    mColor = color;
  }

  public String getColor() {
    return mColor;
  } 
}

Emily,

You got this! The private uninitialized field is a private member variable that has not been initialized. You have :

         private mBarsCount; //What is missing? Variable need a type. What type would a count require?

Also, the instructions say, "Now let's add a private uninitialized field to store the current number of energy bars. Name it mBarsCount. Initialize it to zero in the constructor."

Did you initialize it in the constructor?

I hope these hints can get you on track. Let me know if you need any further assistance though. I am glad to help.

Regards,

Chris

No problem. You are not alone. Many people have a hard time learning abstract ideas in computer languages etc. Remember, when something is easy, you are not learning. It is easy because you already know it. The key is sticking with it to the end and not being afraid to ask for help. Eventually it will become easy and you will realize that you learned it well.

Don't give up!

Regards,

Chris
